CC -!- FUNCTION: This enzyme has both RNase and DNase activity. It CC degrades single-stranded DNA and RNA. CC -!- COFACTOR: Manganese or magnesium. CC -!- SUBUNIT: Homodimer (By similarity). CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane. CC -!- MISCELLANEOUS: The active site contains 1 hydrated divalent metal CC cation that has only 1 direct interaction with the protein; all CC other interactions are via water molecules (By similarity). CC -!- SIMILARITY: Belongs to the DNA/RNA non-specific endonuclease CC family.
